The Xǐguǎn (鼅莞), or Spider District, pattern was a compulsory package of regulations designed by the Party of Yu Jing during the colonization of Yutang and Shentang. Each sector of a new city on the twin planets had to comply with these regulations, which received the name of a symbol of good fortune in Chinese culture. The Xǐguǎn pattern set a series of specific and unavoidable services and modules that guaranteed some minimum, decent conditions for the future inhabitants, according to the ideal of maximum equality for every citizen of the StateEmpire defended by the Party.

This led to the Xǐguǎn becoming the most recognizable visual elements of the first colonization period of Yu Jing’s twin planets. Since they were the oldest sectors of the city and had a basic nature, the Spider Districts were progressively abandoned in favor of newer areas that provided better services and comforts. Inevitably, many Xǐguǎn became areas inadvisable to enter, and the name “spider” lost its positive meaning and acquired the negative sense that we usually attach to these creatures.
